Supplementary Material for the paper "The overflowing atmosphere of WASP-121 b: High-resolution He i 10833 transmission spectroscopy with VLT/CRIRES+" by Czesla et al. (2024).

The material is related to the 3D modeling part of the paper (Sect. 3.5), specifically focused on the atmospheric escape simulations and radiative transfer calculations for the exoplanet WASP-121 b.

We provide the results of the 3D hydrodynamic simulation with Athena++, with key files including the input file and a snapshot of the simulation after 8 orbits.Post-processing is done with a radiation transfer code located in the folder "post-process_W121b". This code, based on MacLeod & Oklopcic (2022), generates synthetic spectra for two density scenarios (scaling factors 0.5 and 1.0) and has been modified for accurate calculations in high density regions. A Jupyter notebook in the same folder illustrates how to analyze the data and generate the corresponding figures.

Detailed descriptions can be found in the README.txt file.
